Add "bounding box" (swlat, swlon, nelat, nelon) values for cities

I'm not sure about the feasibility of this, but here's what I'm trying to do on the frontend:

For a given city (using the city_id value), allow someone to link directly to the coverage map of a certain city, e.g. going to a URL like: https://explorer.helium.com/coverage/cities/:city_id would load up the coverage map centered on that city_id to show the coverage there

I think right now the only way I can see to do it is do a request for https://api.helium.io/v1/cities/:city_id/hotspots and then either loop through all hotspots to get the max/min lat/lon, or pick a random hotspot (or the average of a random sample of hotspots) as a "center" lat/lng value, and then set some reasonable zoom level.

It would be really great if it was possible to get a "bounding box" (swlat, swlon, nelat, nelon) for all hotspots in a given city, so that I could use that as the "frame" to load up in the coverage map. I'm picturing kind of the opposite of this:

/v1/hotspots/location/box with query params swlat, swlon, nelat, nelon to return hotspots within a given geographic boundary

Let me know if you think that might be doable, or if some other solution on the frontend might be better.

talked with bones and he thought of a potentially much easier way to do this—is it possible to get a lat/lng for each cityId on the API side and send it back with city data from /cities?

not sure I'm understanding it all.. multiple h3 locations for hotspots translate to the same city_id.. i.e. multiple lat/lons. You're asking for a single lat/lon that represents a city_id?

yeah if that's possible. not sure what it looks like on the geocoding side but was hoping there was some way we could associate each city_id with a lat/lon that we could use as a center point to snap the map to

if there are several h3 locations that translate to the same city_id that would be workable too if they came back as an array attached to that city_id

I'm just trying to create a way to "link" directly to a given city_id on the map, so whatever's easiest on your side that would give me a lat/lon (or a set of them, or a ne_lat, ne_lon, sw_lat, sw_lon) associated with a city_id would be great :)
